You ask whether a school district trustee may participate in a
health care plan established under section 21.922 of the
Education Code. You note that a trustee is to serve without
compensation. Educ.Code s 23.19(e).

Section 21.922 provides:

(a) The board of trustees of a school district may establish
a health care plan for employees of the district and dependents
of employees.

By its terms, a health care plan established under section 21.922
is limited to district employees and their dependents. See
Attorney General Opinion H-715 (1975) (board members not
"employees"). Consequently, we need not consider whether the
situation you describe would contravene section 23.19(e).
